The Su-34 Fullback, also known as Su-27IB or export code name Su-32, was developed by OKB Suhogo/Sukhoi Joint Stock Company. Russian Air Force ordered in first rate 32 jets in 2008., and later place order for 92 jets in 2012.

Russian Air Force received first two Su-34 in December 2006.

Serial production started in January 2008. Until today (February 2015), Russian Air Force received 65 multi role fighter jets Su-34 Fullbacks, and will not stop on that number.Russian Air Force are in modernization status. Few more years will use Su-24 Fencer as main jet for this role, but plan is that Su-34 take Fencers place here.

Su-34 is a two seater and designed primarily for tactical deployment against ground and naval targets, on solo and group missions in daytime and at night, under favorable and adverse weather conditions and in a hostile environment with counter-fire and EW counter-measures deployed, as well as for air reconnaissance. Because it is based on the Su-27 family, it can also carry out air-to-air missions (interception/air superiority/dogfight), as a secondary role.

The Su-34 replaces for Tu-23M and Su-24 aircraft. Su-34 is one of a number of Russian aircraft, Su-30, Su-33 and Su-35, which are based and developed from the Su-27 Flanker.

The Su-34 design retains the basic layout and construction of the Su-27 airframe, with a conventional high-wing configuration and a substantial part of the onboard equipment. The Su-34 has a changed contour of the nose section to accommodate an advanced multi-mode phased array radar with terrain following and terrain avoidance modes. It has a two-seat rather than single-seat cockpit. The capacity of the internal fuel tanks has been increased with a resulting increased take-off weight. Changes have been made to the central tail boom for a rear-facing radar.

The Su-34’s most distinctive feature is the unusually large flight deck. Much of the design work went into crew comfort. The two crew members sit side by side in a large cabin, with the pilot-commander to the left and navigator/operator of weapons to the right in NPP Zvezda K-36dm ejection seats. An advantage of the side by side cockpit is that duplicate instruments are not required for each pilot. Since long missions require comfort, the pressurization system allows operation up to 10,000 metres (32,800 ft) without oxygen masks, which are available for emergencies and combat situations. The crew members have room to stand and move about the cabin during long missions. The space between the seats allows them to lie down in the corridor, if necessary.A toilet and a galley are located behind the crew seats.Entrance into the cockpit is from below, using a ladder attached to the nose landing gear and a hatch in the cockpit floor. The cockpit is a continuous capsule of armour.

Maximum detection major range for the forward radar is 200–250 km (to review the rear another, aft-mounted, radar is used). The main radar can simultaneously attack the 4 targets (in the air, on land or on the water). The rear warning radar system can warn of attack from behind and it can also attack from behind, without turning the aircraft. Radar defence the rear as claimed unofficially this N-012 radar.

On this infographic you can see potential evolution for Russian PAK-FA T-50 stealth multi-role fighter fifth generation, which will receive code Su-50, when production line starts serial production. Plan for serial production was on January 2016, and will fly under flags of Russia, South Korea, India and Iran.

There are already 5 prototypes.

Sukhoi wants to start producing of special version for Indian Air Force (IAF), which will gets code Su-50E.

If ever South Korean choose to buy Su-50 as their new fighter, they will getting version with local avionics, and jet will get code Su-50EK.

Su-50E have chance to get brother twin seat version co-developed with India for IAF around 2020. year.

In the same year, Sukhoi plans to share with the world Su-55-FGFAM, modernized version of twin seater.

At the end, around 2022. year Iranians are planning to get their Su-50ES version (if ever)

Recently journalists had chance to visit OKB “Sukhoi” and see and look at the new training simulator designed for training pilots multipurpose fighter Su-35.

The Su-35 is a deep modernization of the Su-27 and belongs to a generation 4 ++. The aircraft is designed for air superiority, as well as to destroy air ground and surface targets.

Inside fighter Su-35 is fifth-generation technologies that provide superior fighter in its class. Distinctive differences of the Su-35 to Su-27 are new engines with increased thrust TVC, wide range of aircraft weapons, new avionics based on digital information management system and software, a new set of on-board radio-electronic equipment with a phased array radar and two-stage hydraulic drive, etc… Radar of the Su-35 can detect the type of fighter with the goal of flight efficiency dispersion in three square meters at a distance of about 400 km.

The aircraft has ultra-high maneuverability at low and near-zero rates. This capability is provided through the use of special aerodynamic design and the latest engines with thrust vector control (TVC).

OKB “Sukhoi” plans to make an training complex. It consists of an integrated simulator, procedural and educational computer class flight and engineering technical staff, who are united in a single information and methodological framework that will make all the things complex for training of pilots and engineering staff together.

The class is theoretical training with an automated control knowledge elements and are processed in a procedural simulator and then on the complex, which looks similar to origin cabin of the Su-35 fighter (closing lantern, safety harness, with a spherical dome visualization 270×110 degrees.), and it can practicing almost all kind of processes and problems.

It can be used in network so can connect up to 16 simulators and at the same time perform group training pilots. Over time, it will be possible to combine different types of exercise equipment in one information environs – training -simulator complex. In the future its planned to integrate simulators of other Russian developers.

Integrated simulator purposely is not equipped with mobility system, because the system can simulate only a small part of a large range of highly maneuverable fighter overload, and with mobility will show and display inculcate false skills.

The simulator can perform almost all the same tasks as the pilot is in the plane, including air refueling and the most important thing – testing of emergency situations. This simulator even surpasses the real plane because simulate some troubles and failures situation which are in reality very dangerous, and sometimes impossible. And this is one of the key functions of the simulator.

How does work simulator

Workplace of the Su-35 pilot in full flight simulators is a ventilated enclosed cabin type, where there are everything necessary for comfortable combat mission.
On desk with monitors, outside the cockpit, is instructor place.

The basic controls are: Pilot control stick, engine control levers and pedals.

Information tools are collimator aviation pilot light with a control panel display, which displays flight information, two MFI-35 (multifunction display) every 15 ” control integrated system backup devices, multi-function remote display with a working field 4×5 ” helmet-mounted display system and a voice alarm system.

Multi-function board with a working field 4×5 ” is used to configure all aircraft systems, including radar sighting and navigation equipment, weapons, video recording system.

Automatic thrust control and automatic control system, allows, pilot to keep control a desired rate of movement in all maneuvers and in any conditions or fully automatically keep the aircraft on the route in accordance with the flight plan. The must-do of the pilot is reduced only to the take-off and landing tasks, as well as deciding on the use of weapons.

How we fly here?

First, the instructor make a flight scenario of the exercises with given tactical and meteorological conditions on a real map in a given area. Also, the instructor can quickly enter into a flight or cause failures and faults by monitoring the reactions of the pilot.

Workplace of the instructor is desk with multiple monitors. On the three-dimensional map shows the pivot points, the turning points of the route, and some goals. On another monitor instructor is monitoring the reaction of the pilot, authorities and management and flight parameters. On the third display is general view of the simulator, etc …

Any of the buttons, displays, conditions,…instructor have possibility to zoom in virtual on his monitor.

In fact, flight is happening by itself. The learner is in the cockpit, and the instructor at his workplace. After the training, there is debriefing.

In the photo test pilot OKB “Sukhoi” Sergey Chernyshev performs a test flight and shares his impressions with reporters.

According to Sergei, the philosophy of modern combat mission is as follows: a pilot taking off and waits until the plane automatically to reach a given point; then he decides to use of weapons in accordance with the combat mission (presses the button “defeat the enemy”), waiting until the plane comes back to the base. Thats all.

“The list of tasks to be solved and is already doing this plane is huge. It is characterized by an enormous range of altitudes and speeds, impressive range and endurance, a huge range of weapons that can be used at any time and in any weather conditions. And all these possibilities controls only one person! ”

The designation Su-37 was first used to market a truly multi-role version of the Su-35 (Su-27M) to the United Arab Emirates (UAE) air force. The Su-37MR (MR for multi-role) that was offered would have French-built instrumentation equipment and a number of changes in the avionics. Sukhoi Design Bureau and KnAAPO export company selected the series produced T10M-11 (Su-27M pre-production test aircraft) for conversion, which had already been testing the multi-mode N011M phased array radar. However the UAE preferred the Mirage 2000-9 and it was decided to use the T10M-11 as flying test-bed for the engine thrust vector control (TVC) system. The Su-37 designation was retained.

Su-37 Flanker F – Terminator

Introducing Thrust Vector Control

The TVC system enables the aircraft to direct its thrust produced by the AL-31F engines in a different angle than the flight path on the vertical axis. In high angles of attack, normally an aircraft would stall and the pilot would lose control because of the disrupted airflow over the control surfaces. Also at very low air speeds, the control surfaces no longer function effectively. With TVC the aircraft can still be controlled under these circumstances by using the engines thrust instead of the airflow.

The new Su-37 made its first flight fitted with the TVC engines on 2 April 1996 by Sukhoi’s test pilot Yevgeny Frolov. The aircraft was nicknamed Terminator.

The Su-37’s TVC system is integrated into the aircraft’s fly-by-wire system, giving the aircraft controllability at beyond-critical angles of attack and near-zero speeds. The Su-37 was able of performing aerobatics unmatched by any contemporary fighter. Examples include vertical somersault while retaining the flight path (Frolov’s chakra), forced tight radius turns, controlled spin. This super-maneuverability would give the Su-37 an edge in dogfights with other aircraft. It also stunned the public at the Farnborough airshow in September 1996, Le Bourget in June 1997 and MAKS in August of 1997.

Su-37 near F-16

The Su-37 engine nozzles swiveled only vertically (2D vectoring). Lyulka-Saturn further developed the vectoring nozzle which resulted in the AL-31FP thrust vector control engines capable of moving in both vertical and horizontal axes (3D vectoring). The AL-31FP engine was offered to foreign customers on more advanced developments of the Su-30MK such as the Su-30MKI of the Indian Air Force and as an option for customized versions of the earlier Su-35 ‘Super’ Flanker.

The Su-37’s life ended when T10M-11 (serial 711) was lost in a crash on flying a ferry flight in Russia. The aircraft was not fitted with the TVC engines at the time of the crash. No other Su-27Ms have been converted to Su-37 specifications, nor has the Su-37 design entered production. The Su-37 was never an official designation recognized by the Russian Air Force.

The crash of 711 effectively means the end of the Su-37 as we have known since 1996. The possibility remains that the designation Su-37 will be re-used in the future for other Flanker derivatives. Reportedly, localized Su-35 (Su-27BM) air frames for the Russian Air Force will re-use the Su-37 designation.

Ria Novosti wrote few days ago that Novosibirsk aviation plant (“НОВОСИБИРСКИЙ АВИАЦИОННЫЙ ЗАВОД им. В.П. ЧКАЛОВА”) has filled annual plan for 2014. about supplying Russian Air Force with Su-34 Fullbacks, on time and as was ordered by Ministry of Defense.

Constant modernization of Russian Air Force doing well in last few years and today, and situation is much better than before. Airbases are getting new planes or modernized, all the time, but there are still hard jobs to make Air Force more stronger, even they are now well prepared for any alert actions. They still needs more new planes such as multirole jets Su-35 and Su-34, to be absolutely sophisticated, to make them total air superior air force.

Plant already sent 16 machines to Air Force, and until end of year will send two more – said president of the region.

Novosibirsk aviation plant is one of the largest aircraft manufacturer companies in Russia. Since the early nineties to the present, the company produces multi-purpose fighter Su-34 Fullback.

As a part of the Holding company Sukhoi, in Novosibirsk aviation plant is working on the Sukhoi Superjet 100 (SSJ-100), Russia’s new regional aircraft.

Maybe you already heard that two Su-27s Flankers were sold to American company “Pride Aircraft Inc“, acquired from Ukraine. Both are UB variants, demilitarized, 100% overhauled, better to say `zero-time`, and both were registered as civilian jets. So, they were like new from factory, but without weapon systems,no IRST,…etc.

Software , navigation equipment were changed to western technology. All cockpit markings were relabeled in English. The aircraft have full IFR U.S. instrumentation and avionics, but retain every bit of character, pedigree, and performance they had in foreign military service. Marks of the jets are 31 and 32, but civilian licence registers are N131SU and N132SU.

By information we found, they were sold to Pride Aircraft around 2009 from Ukraine. Pride Aircraft Inc had plans to do some high-altitude research, but company Pride Aircraft went bust and project was terminated. Both aircraft are sold, and price was about $5 million per jet. Customer unknown yet. Here are some photos and videos with both Flankers:
